This specification2 covers a group of general
requirements that, unless otherwise specified in the purchase order
or in an individual specification, shall apply to rolled steel
plate, sheet, and strip, under each of the following specifications
issued by ASTM: Specifications A167, A176, A240/A240M, A263, A264,
A265, A666, A693, A793, and A895.

In the case of conflict between a requirement of a product
specification and a requirement of this specification, the product
specification shall prevail. In the case of conflict between a
requirement of the product specification or a requirement of this
specification and a more stringent requirement of the purchase
order, the purchase order shall prevail. The purchase order
requirements shall not take precedence if they, in any way, violate
the requirements of the product specification or this
specification; for example, by waiving a test requirement or by
making a test requirement less stringent.

The values stated in either inch-pound units or SI units are to
be regarded separately as standard. Within the text, the SI units
are shown in brackets, except that when A480M is specified, Annex
A3 shall apply for the dimensional tolerances and not the bracketed
SI values in Annex A2. The values stated in each system are not
exact equivalents; therefore, each system must be used
independently of the other. Combining values from the two systems
may result in nonconformance with the specification.

This specification and the applicable material specifications
are expressed in both inch-pound and SI units. However, unless the
order specifies the applicable "M" specification designation [SI
units], the material shall be furnished in inch-pound units.
